CY7C419-10JXC

FIFOs Memory Overview

The CY7C419-10JXC is a 256 x 9 asynchronous FIFO memory component manufactured by Infineon Technologies (formerly Cypress Semiconductor). It utilizes dual-port RAM cells to enable independent read and write operations at frequencies up to 50 MHz. The device features a maximum access time of 10 ns, operates on a single 5V supply with an operating current of 35 mA, and includes Full, Empty, and Half Full status flags. It is housed in a 32-pin Pb-Free Plastic Leaded Chip Carrier (PLCC) package.

FIFOs Memory Feature Summary

• Supports asynchronous read and write operations using dual-port RAM architecture
• Provides hardware flow control via Full, Empty, and Half Full status flags
• Enables unlimited expansion in depth and width through dedicated expansion pins
• Includes retransmit functionality for packet data transfer applications

FIFOs Memory Applications

• Asynchronous data buffering between different clock domains
• Packet processing systems requiring data retransmission
• Parallel interface expansion for custom word widths
• High-speed serial-to-parallel conversion buffers

FIFOs Memory Procurement Notes

Verify the specific speed grade suffix matches the required access time, as the '10' indicates a 10 ns maximum access time. Confirm that the JXC suffix corresponds to the 32-pin Pb-Free PLCC package type. Ensure the design accommodates the commercial temperature range specifications provided in the datasheet.

FIFOs Memory Selection Notes

Select this component when a small-capacity, high-speed asynchronous buffer is required. The 256-word depth suits applications needing minimal latency without large memory footprints. Verify compatibility with TTL logic levels if interfacing with older digital systems.

FIFOs Memory Part Context

This part belongs to the CY7C419/21/25/29/33 family of asynchronous FIFOs. The family offers varying depths from 256 to 4K words while maintaining consistent pinouts and operational characteristics across the series. The CY7C419 represents the entry-level depth option within this product line.

FIFOs Memory Replacement Considerations

The datasheet confirms functional equivalence and pin compatibility with IDT7200, AM7200, and similar legacy devices. Verify voltage tolerances and timing parameters against these alternatives before substitution.
